Then, when the user performs an operation for ending the 2-cell one-segment viewing function on the operation-side mobile phone, this function is stopped. In addition, when two mobile phones are separated, this function is configured to automatically stop.

  In the following preferred embodiment, a mobile phone is used as a mobile terminal and a case of two mobile phones will be described. However, such an embodiment is merely an example, and a mobile terminal having a display (image display unit) in general. Thus, the present invention can also be applied to the case of three or more units. In any case, a state in which a plurality of portable terminals are arranged may be held by means such as a holder.

[Configuration of Example]
An embodiment of the present invention will be described with reference to FIGS.

1. Activation Method When two mobile phones are arranged side by side on a plane so that the sides in the longitudinal direction are parallel to each other, the 2-cell one-segment viewing function is automatically activated. The mechanism to start automatically is as follows. The configuration of the mobile phones arranged side by side is the same, and one mobile phone 100 will be described below.

  The cellular phone 100 according to the present embodiment is equipped with two magnetic sensors and two magnets (detected parts) as means for automatically starting the two-portable one-segment viewing function. In the following description, the right side and the left side mean the right side and the left side when facing the mobile phone.

  FIG. 3 shows an example of the location of the magnetic sensor and magnet to be mounted. The reference numbers corresponding to the case of the other mobile phone 200 are shown in parentheses. A magnetic sensor 102-1 (202-1) is mounted on the upper left side on the LCD 101 (201) side, a magnet 103-1 (203-1) is mounted on the upper right side, and a magnet 103-2 (203 is mounted on the upper left side on the operation unit side. -2), the magnetic sensor 102-2 (202-2) is mounted on the upper right side.

  The combination of these magnetic sensors and magnets will be described in detail with reference to FIG. 4, but when two mobile phones are arranged in a predetermined arrangement pattern, the side facing each other adjacent mobile terminals There may be a configuration in which there is a magnet in one of at least two places on the edge, and a magnetic sensor that detects the presence or absence of a magnet in the other portable terminal adjacent to the other of the at least two places. In other words, when there are two pairs of magnetic sensors and magnets, the magnetic sensor is located in one of the two pairs of squares and the magnet is located in the other pair. There is no problem even if the order is reversed.

  According to the arrangement of the magnetic sensor and the magnet as described above, as shown in the upper diagram of FIG. 4A, the magnetic sensor 202-1 on the LCD 201 side of the mobile phone 200 placed on the right side is placed on the left side. When the magnet 103-1 on the LCD 101 side of the mobile phone 100 is detected and the magnetic sensor 102-2 on the operation unit side of the mobile phone 100 detects the magnet 203-2 on the operation unit side of the mobile phone 200, the mobile phone 100 Determines that the mobile phone 200 is placed in the right place on the left side and the mobile phone 200 is placed on the right side, and automatically activates the 2 mobile one-segment viewing function. Such determination means relating to the arrangement of the mobile phone and automatic start means for the two-portable one-segment viewing function will be described later.

  The lower diagram in FIG. 4A shows a case where the mobile phone 100 and the mobile phone 200 are placed opposite to each other, but the magnetic sensor 102-1 on the LCD 101 side of the mobile phone 100 placed on the right side is placed on the left side. When the magnet 203-1 on the LCD 201 side of the mobile phone 200 is detected, and the magnetic sensor 202-2 on the operation unit side of the mobile phone 200 detects the magnet 103-2 on the operation unit side of the mobile phone 100, FIG. As in the upper diagram of FIG. 4 (A), the 2-cell one-segment viewing function is automatically activated.

  On the other hand, FIG. 4B shows a case where it can be determined that the two mobile phones 100 and 200 are not correctly arranged. As can be understood from FIG. 4B, when one of the two mobile phones is arranged upside down, upside down, and upside down, the two of FIG. Since the conditions of the example are not satisfied, the 2-cell one-segment viewing function is not activated.

  In this way, on the mobile phone 100 side, when the right magnetic sensor 102-2 detects the magnet, the mobile device 100 is determined to be arranged in a predetermined arrangement pattern, and the placement position is determined to be the left side of the arrangement pattern, When the left magnetic sensor 102-1 detects the magnet, it is determined that the device is arranged in a predetermined arrangement pattern, and that the arrangement position is on the right side in the arrangement pattern. The same applies to the mobile phone 200.

  Note that the automatic function of the two-portable one-segment viewing function using a combination of a magnetic sensor and a magnet is merely an example, and may be realized by employing another known method.

2. Screen Display Method FIG. 5 is a block diagram showing a configuration example of a mobile phone according to the present embodiment. Similar to conventional mobile phones, the mobile phone 100 includes an LCD 101, a one-seg broadcast receiving unit 104 for receiving one-seg broadcast data, a one-seg control unit 105 for controlling one-seg viewing functions such as channel control and screen display setting, and Bluetooth communication. Bluetooth control unit 106 for controlling As is well known, the Bluetooth control unit 106 identifies an adjacent mobile phone in a state where the mobile phone is placed in an arrangement pattern as shown in FIG. 4A apart from the original communication function of the mobile phone. However, it has a function as communication control means for exchanging simple information.

  Next, blocks added to the mobile phone 100 according to the present embodiment will be described. The cellular phone 100 includes a magnetic sensor monitoring unit (monitoring unit) 107 that detects the presence / absence of a detection event generated by the magnetic sensors 102-1 and 102-2. The magnetic monitoring unit 107 functions as a determination unit that determines whether the own device is arranged in a predetermined arrangement pattern together with the magnetic sensor and the magnet. The mobile phone 100 also determines the placement position of the mobile device based on the detection event detected by the magnetic sensor monitoring unit 107, and a screen portion (here, to be displayed on one large screen according to the determined placement position) Then, it has the 2 portable display control part (display control means) 108 which determines a half screen. The two-portable display control unit 108 performs activation control of the two-portable one-segment viewing function, cooperates with the one-segment control unit 105, and transmits channel data and the like to the Bluetooth control unit 106. The mobile phone 100 further includes a display screen constructing unit 109 that receives the one-segment broadcasting data and information on the screen portion to be displayed via the one-seg control unit 105, creates a half-image to be displayed, and adjusts the resolution thereof.

  In addition to the above, the cellular phone 100 omits illustrations and detailed explanations, but includes an operation unit (operation means) composed of a plurality of key input units and a control program necessary for executing the control operation described below. Needless to say, the mobile phone has the functions provided so far, such as a storage device including a storage unit that stores various information for realizing various functions of the mobile phone. 2 The portable display control unit 108 is connected to the storage unit, receives key input information on the operation unit side via the one-segment control unit 105, and executes a control operation described later.

  Also in FIG. 5, reference numerals corresponding to the case of the other mobile phone 200 are shown in parentheses.

  2 When the portable display control unit 108 receives the detection event from the magnetic sensor monitoring unit 107 while the one-segment viewing function is activated, the portable display control unit 108 determines whether one of the two conditions described with reference to FIG. At the same time, it is determined whether the mobile phone is placed, that is, on the right side or the left side. 2 As a result of the determination, the portable display control unit 108 instructs the one-seg control unit 105 to pass the received one-seg broadcast data to the display screen construction unit 109 if either one of the two conditions is satisfied. At the same time, the mobile phone placement position information (right side, left side) is also notified.

  When receiving an instruction from the two-portable display control unit 108, the one-seg control unit 105 stops outputting the one-seg broadcast data to the LCD 101, and sends the one-seg broadcast data and placement position information to the display screen construction unit 109. The display screen construction unit 109 that has received the one-segment broadcasting data and the placement position information constructs the one-segment broadcasting data for dividing the one-segment broadcasting data into two based on the placement position information of the mobile phone and displaying the half moving image on the LCD 101. . The constructed one-segment broadcast data of the half image is sent to the LCD 101 and is enlarged and displayed twice on the LCD 101.

  Since it is necessary to synchronize with the other mobile phone (hereinafter sometimes referred to as the opposite device 200), the two portable display control unit 108 communicates with the opposite device with respect to the Bluetooth control unit 106 that controls Bluetooth communication. Request the establishment of the Bluetooth communication channel, and transmit the channel information (instruction information) including the currently displayed channel number to the opposite device after the communication channel is established.

  Receiving the channel information from the mobile phone 100, the opposite device 200 links its own one-segment control unit 205 and the two mobile display control unit 208 to construct a display screen that is half the reverse of the half image on the mobile phone 100 side. It is constructed by the unit 209, sent to its own LCD 201, and enlarged and displayed twice on the LCD 201. At this time, in the opposite device 200, the mobile phone 100 has been described using the magnetic sensors 202-1 and 202-2, the magnets 203-1 and 203-2, and the magnetic sensor monitoring unit 207 shown in FIG. In the same way, it knows its own position.

3. Channel change method Channel control during viewing by the 2-portable 1Seg viewing function is performed on the side where the 2-portable 1Seg viewing function is activated (hereinafter sometimes referred to as the operating-side mobile phone 100), and is not performed on the opposite device 200 side. When the user changes the channel on the operation-side mobile phone 100, channel information including the channel number is notified to the two mobile display control unit 208 on the opposite device 200 side via Bluetooth communication via the one-segment control unit 105 and the two mobile display control unit 108. Is done. Upon receiving the notification, the two portable display control unit 208 on the opposite device 200 side passes the channel information to the one seg control unit 205, and thereafter, the half image of the changed channel is enlarged and displayed twice on the LCD 201 in the same manner as described above. .

4). Termination Method When the user operates the predetermined key input unit on the operation-side mobile phone 100 to end the two mobile one-segment viewing function, or when the two mobile phones 100 and 200 are released, the magnetic sensor monitoring unit 107, When it is determined that the detection event from 207 disappears and the two portable display control units 108 and 208 can no longer satisfy the condition of FIG.

[Operation of the embodiment]
The operation of the above embodiment will be described with reference to FIG. Hereinafter, for convenience, the control operation will be described separately for the operation-side mobile phone and the counterpart device, but it goes without saying that the mobile phone has both control operation functions.

  The control flow (left side in the figure) of the operation side mobile phone 100 and the control flow (right side in the figure) of the opposite device 200 will be described in detail. The following control is realized mainly by the two portable display control unit 108 (208) reading and executing a control program stored in a storage unit (not shown).

  First, when the user presses a predetermined key input unit on the operation-side mobile phone 100, the operation-side mobile phone 100 receives this as a trigger and thereafter functions as the operation side. In other words, the mobile phone that has received the instruction information from the operation-side mobile phone 100 with no trigger input becomes the opposite device.

  When the two mobile phones 100 and 200 are brought close to each other, each magnetic sensor notifies the magnetic sensor monitoring units 107 and 207 of the detection event. ). In the case of the pattern of FIG. 4A (steps A1 and B1), the operation-side mobile phone 100 checks whether the one-segment viewing function is being used (step A2). If the one-segment viewing function is not used, there is no need to activate the two-portable one-segment viewing function, so the flow ends without doing anything.

  If the one-seg viewing function is activated on the operation-side mobile phone 100, a pop-up asking whether to use the two-mobile one-seg viewing function is displayed on the LCD 101 (step A3), and the user's selection operation input is awaited. (Step A4). When a selection operation using the 2 mobile one-segment viewing function is performed using the key input unit, the operating-side mobile phone 100 exchanges information with the opposite device 200 via Bluetooth communication to synchronize with the other device 200. When different mobile terminals other than the counterpart device 200 exist in the communication range, all the mobile terminals existing in the Bluetooth communication range are displayed on the pop-up screen and displayed so that the user can select the correct counterpart device. If it is determined in step A4 that the user has selected “use”, Bluetooth connection is started and a Bluetooth network is established with the opposite device (step A5).

  On the other hand, since the predetermined key input unit is not pressed in the opposite device 200, after the determination of the pattern in FIG. 4A in step B1, the operation side mobile phone 100 requests the activation of the 2 mobile one-segment viewing function. Wait for whether there is a Bluetooth connection request that arrives at this timing as a request to activate the 2-cell one-segment viewing function (step B2), and if there is no request after a certain period of time, the control flow ends. If there is an activation request within a certain time, Bluetooth communication with the operation-side mobile phone 100 is permitted (step B3). Thereafter, the channel information being viewed is sent from the operation-side mobile phone 100 to the opposite device 200 (step A6). Receiving the channel information from the operating-side mobile phone 100, the opposite device 200 determines whether or not the one-segment viewing function is being used in step B4. If the opposite device 200 has not activated the one-segment viewing function, the one-segment viewing function is activated. After activating the function (step B5), the channel is changed to the channel of the received channel information (step B6). Thereafter, a half image that is symmetric between the respective mobile phones 100 and 200 is constructed by the respective display screen construction units 109 and 209 and enlarged and displayed on the respective LCDs 101 and 201 in a doubled manner (steps A7 and B7).

[Effect of Example]
According to the above embodiment, the following effects can be obtained.

  The first effect is that the user can view the one-segment broadcasting on a larger screen. The reason is that, in order to secure a double screen size, two mobile phones can be used, and left half and right half moving images can be generated and synchronously enlarged and displayed.

  The second effect is that the two-cell one-segment viewing function can be activated only by placing two mobile phones side by side without complicated settings by the user. The reason for this is that a combination of a magnet and a magnetic sensor attached to the mobile phone is used to determine whether or not each mobile phone is arranged in a predetermined arrangement pattern with respect to other mobile phones. This is because the position (left and right) of the mobile phone in the mobile phone is detected, and based on this, the 2 mobile one-segment viewing function can be automatically activated.

  The third effect is that the channel change performed by the user may be performed only by the operating-side mobile phone. The reason is that a device capable of constantly transmitting / receiving channel information by using the Bluetooth communication function is installed.

  The fourth effect is that an enlarged image can be displayed without always exchanging information between the operating-side mobile phone and the opposite device.

[Other embodiments of the invention]
Next, another embodiment of the present invention will be described. In the above embodiment, a method of securing a double screen size by using two mobile phones has been exemplified. However, by using three mobile phones or four mobile phones as shown in FIG. A method of securing a double screen size can also be realized. In the arrangement form of FIG. 7, two sets of two mobile phones arranged as shown in FIG. 4 (A) are prepared and arranged so that the short sides of each set of LCDs face each other. An arrangement in which the units are arranged may be used. In the case of three units, they are arranged side by side, both sides are detected in the same detection mode as in the above embodiment, and the center is determined by determining that both are located in the center of the arrangement pattern when both magnetic sensors detect the magnet. be able to.

  In the above-described embodiment, viewing of one-segment broadcasting by a mobile phone is targeted. However, a viewing mode that targets, for example, JAVA games can also be realized. In this case, in addition to a mode in which a plurality of mobile terminals are used to display a multiple display on a single screen and a game is played by one person, a multiple display is provided using multiple mobile terminals. It is possible to realize a mode in which a game is played by a plurality of people by displaying it on the screen.

  The present invention is not limited to a mobile phone, and can be applied to all mobile terminals having a display such as a PHS (Personal Handyphone System) and a PDA.
